Patented Dec. 23, 1941 UNITED STATES PATENT OFFICE 2,267,022 PORTABLE LEVELING BATCH BOX Edward 0. Gledhill, Galion, Ohio. Application August 3, 1938, Serial No. 22?;914

2 Claims.

therefore, to provide a portable leveling batch box which after being filled from a dump truck, may be shifted to straddling position above a hole 'to be filled, and then opened for allowing material in the box to fill the hole.

Another object of the invention is to provide a batch box of this character which, after a hole has been filled with road repairing material, may be shifted for removing the unused material and providing an even unobstructed upper surface for the road. j

A further object of the invention is to provide a portable leveling batch box having a plurality of gates or aprons thereon which will be operable for permitting the spreading of road repairing material either in a narrow strip or in wider strips. 7 7

As a further object, the invention seeks to provide aportable leveling batch box wherein the aprons employed are adjustable to any de sired height so that any desired elevation of repairing material may be laid on the road.

As a further object, this invention seeks to provide a portable leveling batch box which is characterized by the utmost simplicity and which may be manufactured cheaply.

Other and incidental objects of the invention not particularly pointed out hereinabove will become apparent during the course of the following description.

My improved portable leveling batch box is illustrated in the accompanying drawings forming a part of this application, wherein:

Figure 1 is a side elevation of the complete batch box,

Figure 2 is a longitudinal sectional View of the device,

Figure 3 is a horizontal sectional view on the line 3-3 of Figure 2,

Figure 4 is a vertical sectional view on the line 4-4 of Figure 1, and

Figure 5 is a vertical detail sectional view on the line 5-5 or Figure 4.

Referring now to the drawings in more detail,

it will be seen that similar characters of reference designate like parts throughout the various views. The numeral l indicates in general a hopper which has an open upper end 2 and an open lower end which is closed by a slidable wall or gate 3, The hopper has an incli-ned forward wall 4 and a vertical wall 5 and said hopper also has verticalend walls 6 and 1, A reinforcing bead 8 surrounds the upper riniof the hopper and said bead is in the form of an inverted L-shaped metal strap. The hopper is supported on runners 9 and I9 which are located near the walls 6 and l and are disposed parallel spaced relation to said walls and to each other. The runners 9 and lllhave standards II and I2 which are upstanding from the substantially mid portions of said runners. Each of the standards includes supporting members I3- and M which converge and are connected at their upper ends by a bearing plate IS. The bearing plate [5" has a bearing l6 thereon which journals aneccentric trunnion l'( and has rotatably mounted therein a stub shaft 18 which carries a wheel l9 atits free end. It should be understood that this structure is duplicated at each side of the batch box so that a pair of wheels, with mounting means therefor, will be provided.

Surrounding the eccentric trunnions between said trunnion andthe bearing I6 is a sleeve 29 which has an operating plate 2| secured toits outer end. The operating plate 21 receives one of the free end portions 22 of 2'. raising lever 23 which is substantially U-shaped in contour and straddles-the batch box. It will be understood that the lifting" of the lever 23 will rotate the eccentric trunnion l-l through a portion of a revolution and will simultaneously raise the runners 9 and I9 and lower the wheels I9 into engagement with the ground so that the device may be moved along on the wheels [9. Lowering of the levers 23 will, of course, return the runners to contact with the road surface and will raise the wheels I9 out of contact therewith.

The gate 3, which closes the bottom of the hopper l, is slidably mounted on guides 24 which are fixed to the runners 9 and I0 and are upwardly obliquely disposed. The guides are, as will be understood, of an inverted L-shaped contour so that the gate 3 will be effectively slidably mounted on said guides and in proper relation to the hopper 4. In order to operate the gate, a lever 25 is provided. The lever 25 extends above the upper surface of the hopper 2 for manual engagement and has its lower end connected with a cross rod 26. The cross rod has its end portion journaled in bearings 21 and 28 which form parts of brackets 29 and 310. The brackets 29 and 30 are connected with the hopper at opposite sides thereof. The cross rod 26 has operating links 3| and 32 connected at its free end and said operating links have inwardly ofiset portions 33 and lower end portions 34 which are handles 49, 50 and 51 also have relatively long manually engageable portions 56 which extend above the upper rim of the hopper I. It will be understood that the handles 49, 50 and 5| are to be rocked toward the vertical for raising the aprons 39, 40 and 4| and permitting the discharge of material behind the batch box in any suitable height, if such discharge is desired. In other words, the aprons 39, 40 and 4| are selectively controllable so that either a wide strip of material, the entire width of the batch box if desired, a narrower strip of material, or no material at all may be left behind the batch box as the same is moved forwardly after dropping material into a' hole to be filled. If all of the aprons are allowed to remain in their lowermost so that the contents of the hopper will be confined therein. When the lever is moved to the position Shown in dotted lines in Figure 2, the gate will be moved to opened position, also shown in dotted lines, when the contents of the hopper will be allowed to flow therefrom. Attention is called to the fact that the rear end of the gate 3 is, when in closed position, disposed nearly adjacent the surface of the ground on which the device is resting. Therefore, when the gate is opened, the material will be nearly at ground level when being discharged. Possible wasteof material will be avoided by the use of.

this construction. V e

In order to level offa surface after being treated with road repairing material, I provide a plurality of aprons 39, 40 and 4!. The aprons are slidably mounted in guides 42, 43, 44 and' 45 which are carried on the rear wall 5 of the hopper" I. It will be seen that, by referring to Figure 4, the guide 43 is common to the aprons 39 and 40 while the guide 44 is common to the opposite end of'the apron 40 and the mating edge of the apron 4!. The aprons 39, 40 and 4| are disposed in close parallel spaced relation to each other,

however, so that there will be no possibility of road material escaping between mating edges of said aprons. Moreover, material will be prevented from escaping past the corners of the batch box. Links 46, 41 and 48 extend vertically along the wall 5 of thehopper l and have their corresponding lower ends connected with the aprons 39, 40 and 4|, respectively. Raising handles 49, 50 and 5|, which are substantially angleshaped in contour, are pivotally mounted on the wa1l5 by means of bolts 52, 53 and 5 4. The raising handles have relatively short arms 55 which are connected with the links 46, 41 and 48 at their upper corresponding ends. The raising position, said aprons will scrape oif any unused material from a hole, after filling the same, so

that a smooth even upper surface will be provided for the roadway.

tion of my improved portable leveling batch box will now be thoroughly understood.

Having thus described the invention, what is claimed as new is: I

1. In a portable leveling batch box, a hopper, means supporting the hopper above a road surface, guides carried by said hopper, a gate slidable on said guides and normally closing the lower end of the hopper, bearings connected with the hopper, a cross rod having its ends journaled in the bearings, a lever carried by the cross rod for manual engagement, a link connected with the cross rod, and an operating rod connecting the link with the gate, said lever being operable for opening and closing the gate for controlling flow of material from the hopper. v

2. In a portable leveling batch box, a hopper having a rear wall formed with openings near'its lower end, means for supporting thehopper over a surface to be treated,-guides carried on the rear of the hopper adjacent the openings, a plurality of aprons slidab-le in the guides, a plurality of handles on the hopper above the aprons, and links operatively connecting the handles with the aprons, said aprons being selectively operable by said handles for leveling'off a surface of a desired width and thickness.
